What is the vague pronoun in this sentence?

SENTENCE: Am I next, or are they?

jessica, a teenage girl who just wants popularity, does everything to get attention. she puts her hair in a bun and steals her mom's lipstick and such. but then she takes something and it makes her inside and outside appearance  go bad.

i just came up with that in less than 60 seconds, but tweak it up if you like it.

explanation:

you didn't give a theme but i did a question like this a while ago so i hope this is what you were looking for.

the correct answer is option d. none of these. it is noted that options a, b, and c share the same content.

despite the valid answer provided at the last sentence of each of the options, a question/answer format shouldn't include humourous themed responses such as "you bet your thermal pj's we do." - unless of course, the answer is carried out in an informal environment. this could be replaced with a simple "yes" or "it is necessary".

the question should be re-phrased to a more appropiate syntaxis. instead of "do we need the greenhouse effect? ", it should be written as "is the greenhouse effect necessary? " in order to give it a general scope, instead of limiting the answer to the needs of "we" the humans.
